The bottom half (approximately) of each element of Bill's 4-square is Rohn
25, and the rest is a stinger (aluminum tube) that goes up to whatever

Similarly, the Ham Sticks I use for mobile operating consist of a coiled
lower section and an upper stinger that is adjusted for resonance.
I had forgotten that Bill talks about his 4-square on his web site. Take a
look here: http://w4an.contesting.com/80m.htm
